FCP 5.1.4 and Kona 3 - problem downconverting
on Jul 26, 2007 at 5:13:34 pm




I've been working with the Kona 3 now for a few months and it's great. However recently it started acting weird and I'm not sure what to do. I've looked everywhere and can't seem to find a solution.

Here's what's going on.

I am trying to digitize a 1080i source from a Sony SRW-5500 deck and down convert it to 525. The Kona control panel is set to 1080 source, 1080 frame buffer, and down convert to 525 on SDI1. When I go into FCP, my easy set up is set for 525 10bit. My external monitor shows the image @ 525. All is well up to here.

Then I open the capture tool. The Kona card immediately switches back to 1080i on SD1. My external monitor also changes - it continues to show a 525 image, but that image is the upper corner of the original 1080 source. It's like it zoomed in on it.

Is this a bug? Am I missing a setting? Any help is greatly appreciated.

Thanks
Mark Santora

What happens when you start to play the tape?

You should set up the 10 Bit SD easy setup and be good to go. Make sure you select the type of down convert you want in the Control Panel (letterbox, crop, etc.)

I have the easy setup set at 525 and the downconvert set up for letterbox. it's strange. I just won't let me do it.

My source says 1080, the frame buffer say 1080, the down convert says 525, then the SDI 1 output says 525. The primary is set to 1080 and the secondary to 525.

Any ideas?

Thanks

Set your primary to 525, secondary to 1080. Down conversion on the way in acts a little differently than down conversion on the way out.

That did it. Wow. I would never have thought to make the primary 525. After all, the primary format (from the tape) is 1080! I guess the way my brain works is that you have to identify the incoming stream and then tell it to convert to whatever you need. Obviously not how the Kona works.

Thanks for the help Jeremy.

No worries. Glad you are up and running.
